...in TX the utility company owns the electric and gas companies so a heat pump will not help much...unless gas isnt available then a heat pump would work best. As for which brand, it would probably depend on who your contractor reps.

You'd be hard pressed to show me anywhere in the US where the add-on heat pump costs more to operate than the most efficient gas only system.

Your going to hear every brand offered here so take it with a grain of salt. If you want to go gas only (or even keep the HP) and you want the ultimate in comfort go with the Rheem Mod90. You wind find much in the way of dispute with that by anyone who has seen or owned it. You may however get some grumbles from the guys who have only heard of it.

American Standard & Trane have had some serious problems with the R410a heat pumps, outdoor units are not built as well as expected. Multible leaks develope within a few months of operation. We have sent 29 units back due to leaking issues, however we have repaired 18 units before we came to an agreement to start returning them. So thats 47 units total that have had leaking issues out of 54 we installed. (Leaking occured inside the outdoor unit) this is a factory quality problem. At this point we will not sell a trane or american standard R410a system! Buy a Rheem.

I can agree with the Trane R-410a systems... That is why I would recommend keeping a dual fuel set-up with a Carrier system, NOT INFINITY... Heat pumps are economical to run during warmer times (32-70 outdoor ambient) and can actually give you better cooling...

That's interesting coolguy and cde. How old were the systems you had problems with. Were the systems installed on new construction, change out, retrofit? We all know that new construction is the hardest on a new system. The company I work for averages about 20 heat pumps a month with about 12 of those being 410a systems. The only real problem I know of is the factory recall on the XL19i, but that's an R22 system.

I'd highly recommend the Infinity Control,we have had no probelms,customers love them.

Use the search function,on this site to see what homeowners think about them!

The installations were change out's, 2 were new construction jobs. We have stopped using them for about 6 months now, July of 2004 wat the last one. Primary location of leak, was inside the cabinet on the right side, on the coil header. We will not install American Standard or Trane 410a systems unitil we feel the problems have been addressed and corrected. Not picking on Trane here, I worked for Trane as a field service manager for years, they have great equipment, and I still sell American Standard & Trane commercial systems.

I'm assuming you are around Pittsburgh somewhere, you can draw an imaginary line somewhere around cincinnatti and extend it in both directions, anything above that line is Nat Gas territory and below it heat pumps start looking good.

I would buy a Rheem, it is the best bang for the buck. If you want to spend your money in a cost effective manner. If you insist on paying for name recognition then buy a Carrier, but you don't get anything extra out of it.
